G125-FV15005F3R

Overview

The Harwin G125-FV15005F3R is a Gecko-SL series power-to-the-board connector featuring a 1.25 mm pitch and 50 positions in a dual-row configuration. It utilizes female socket contacts with gold plating on beryllium copper, rated for 2 A current and 250 V/450 V voltage. Designed for vertical surface-mount installation via solder pin termination, the housing is constructed from green nylon. The component operates within a temperature range of -65 °C to +150 °C and offers high reliability with 1000 mating cycles.

Feature Summary

• Patented four-finger copper alloy contact design ensures secure connection and high durability under extreme vibration conditions.
• Reverse fix mounting mechanism provides enhanced mechanical stability and secure board attachment for surface-mount applications.
• Low-profile miniature package architecture delivers significant space savings compared to traditional high-performance connectors.

Applications

• High-reliability electronic product designs requiring compact interconnect solutions
• Applications subject to extreme environmental conditions including wide temperature ranges
• Systems demanding resistance to severe Z-axis vibration environments

Procurement Notes

Verify that the specific reverse fix variant matches the mechanical constraints of the target PCB layout. Confirm that the 1.25 mm pitch aligns with existing footprint requirements. Ensure compatibility with automated pick-and-place processes if tape-and-reel packaging is utilized for assembly efficiency.

Selection Notes

Select this model when a vertical female header with reverse fixation is required for dense power or signal routing. Consider the 2 A per contact rating for circuit load analysis. Evaluate the -65 °C to +150 °C operating range against environmental specifications to ensure long-term performance stability in demanding operational scenarios.

Part Context

This component belongs to the Harwin Gecko-SL family, engineered for high-reliability interconnects in miniature packages. The series leverages a 1.25 mm pin spacing to achieve substantial space reduction over larger connectors like Micro-D. It supports both signal and power transmission with robust contact technology proven for extreme operational environments.

Replacement Considerations

Compatible counterparts within the same series include G125-FV15005L0R and G125-FV15005F3P. Verify that alternative part numbers maintain identical reverse fix mounting characteristics and vertical orientation before substitution to ensure mechanical fitment consistency.
